摘　　要：本文在了解红热外成像技术及其发展现状的基础上,研究了架空输电线路绝缘子串发热机理和温度分布异常的原因,并运用ANSYS有限元分析软件对不同工况下绝缘子串的温度分布进行仿真计算。然后对运行中的绝缘子串进行实测,即使用红外热像仪采集输电线路中绝缘子串的红外热成像图谱,并进行绝缘子温度异常的案例分析。最后将仿真结果与案例图谱进行对比分析,论证红外热成像技术在架空输电线路绝缘子状态检测中的可行性和有效性。Based on obtaining some knowledge about infrared thermal technology and what level it has developing, the paper studies heating mechanism of overhead transmission line insulator string, and reasons for insulator string＇s abnormal temperature. Then we can use ANSYS that can simulate temperature distribution of insulator string under different conditions. Mter that, some running insulator strings are detected by infrared thermal imager, and some abnormal insulator string＇s infrared thermal images are analyzed. In order to demonstrate the feasibility and availability that infrared thermal imaging technology is used in condition based maintenance of overhead transmission line, the simulation results are compared with infrared thermal images that are collected from running abnormal insulator strings.
